Color blindness affects 8% of all men and 0.5% of all women. There are different types of color blindness and much more to it than meets the eye. If any of this is news to you, then this is the perfect article to catch you up on some of the color blindness facts and what to look for, what not to say, etc.

1. 99% of all color-blind people are actually color deficient, meaning that they are unable to see certain colors on the spectrum or some colors look like others due to the wiring inside their eyes and brain.

2. Color blindness is split into three categories: protan, deutan, and tritan defects. More on each of these later, but each defect changes how a person perceives certain colors on the spectrum. This can make color based learning in the early years of school tough, while also potentially hindering a person later in life, so it's best to learn early and try to find ways to work around the deficiency to better help you down the road.

3. Protanopia is one of the red-green color blindness's, meaning that those affected have difficulty distinguishing between blue/green and red/green. This color blindness makes driving difficult and dangerous due to the coloration of stoplights.

4. The second red-green color blindness is deuteranopia, which is similar to the first type, but those afflicted by this type have trouble with greys, purples, and variations of green and blue. There are also two versions of this type. The first is dichromats, who are only able to see 3 hues due to the lack of green cones in their eyes. The second is anomalous tricromats, who can range from normal color vision to deuteranopia.

5. Tritanopia is the yellow-blue color blindness. More specifically, those affected by this type have trouble distinguishing between blue/green and yellow/violet. This type is very rare and at best, only affects 1 in 10,000 people.

6. Strongly colorblind people may only be able to distinguish between 20 different hues, when most people are able to differentiate between over 100 hues.

7. Color blindness is divided into 4 categories: slight, moderate, strong, and absolute. Those with absolute color-blindness make up only 1% of all color-blind people, as having no color cones in their eyes is very rare and results in shades of white, grey, and black.

8. Although only 0.5% of all women are colorblind, there are more women carriers of colorblindness than men, even if they aren't even colorblind.

9. If a woman is red-green colorblind, all of her sons will be red-green colorblind as well. However, a man can't pass on his red-green colorblindness to his sons.

10. There is currently no cure for colorblindness. If you or someone you know shows signs of color blindness, it should be checked out immediately so that they can continue to live comfortably.

Hopefully these colorblindness facts have helped some of you realize how serious this deficit is and how important it is to make sure it is discovered early and dealt with sooner rather than later.
